An<i>in vitro</i>evaluation of the accuracy of four electronic apex locators using stainless-steel and nickel-titanium hand files

Abstract

The results of this study indicate that Root ZX was statistically more accurate with NiTi files compared to SS files, while MINI was statistically more accurate with SS files compared to NiTi files. ELE and PIXI were not affected by the alloy type of the file used to determine WL.
